Here in Brazil we have rampant violence. Criminal and 'lawful' violence.
The police is itself violent with the civilians, suspects, criminals, mostly with the poor or non-whites.
In that way it looks a lot like the US. But there is a difference here, in which the great marjority of the middle-class are supporters of it, the deathrow, and mainstream news anchors who deliberately promote lynching against perpetrators caught redhanded for simple crimes (as lets say, pickpocketing), suffering little to no criticism from their colleages, most having alleged that the police is under-resoursed for dealing with crime so "they might need a hand sometimes". It's a full plate for human rights NGO's throughout the world.

My idea has to do with a memetic broadcast manifestation that scales that to over 9000, and risks infecting event Foundation staff, deeply changing how crime is perceived and dealt with.

Eventualy, the infected lynching vigilantes perceive themselves as criminals, and that the only way the world can be purged from crime is killing everyone. Or something like that. I also think that working something involving how this anomaly can affect the Foundation pool of Class D can enrich its content. English is not my first language so I might need assistance in developing the idea.

The entity responsible for it can be vaguely perceived while an Sheherazados-Class Event is being broadcasted, as fear for the well being of self and others is infused in to watchers.

I punched a few letters on the keyboard and the following is what I have for now. Few free to throw as many punches as you'd like haha
Also, its my first work here

Special Contaiment Procedures:Site-████ level 3 personnel assigned to the containment of SCP-YYYY and a stationed subdivision of MTF Pi-1, Mobile Task Force c-b4 “Tanned Hides” are to monitor local media and news stations for signs of violence spikes amidst local population of ████████, São Paulo, Brazil. In case of criminal activity amidst staff stationed at the Site, ████████ of the bastard is the only viable option of containment.
Field agents scoring no less than 98 at the infohazard resistance test are to be embedded at the local ████ Network Station production staff to further monitor local news anchors for signs of gradual deviation from the scripted reporting.

Following Incident- YYYY 01, local media and news stations are to be monitored using the current version of the multipurpose Silvo-Ikesak infohazard detection A.I. program for signs of SCP-YYYY-1.
Since differentiating local cultural behavior from early anomalous deviation in the populace is difficult, research efforts are currently focused on media detection and censoring of the anomaly.
Research on contaiment of SCP-YYYY-1 is ongoing. Personnel contact with affected material must be done through memetic filtering agents, and must take weekly tests for memetic infection and psychiatric evaluation.
In case of a Sheherazados-Class Event breach, enactment of Some-Luz Procedure is imperative. All hydroelectric power stations of the brazilian southeastern region are set to be remotely deactivated, further preventing spread of SCP-3906-L. Mobile Task Force c-b4 must be deployed in affected areas and instances of SCP-3906-L must be terminated on sight. Local populace is to be screened for infohazard infection and unaffected individuals are to be administered with Class-B amnesics. A cover story of mass commerce pillaging followed by a powergrid blackout is to be disseminated through the media and populace.
Worldwide personnel responsible for Class-D handling are to be weekly screened for memetic infection of SCP-YYYY, and are under no circumstances introduced to the contents of this document or any concept or reproduction SCP-YYYY, risking a global scale containment breach.

Description: SCP-YYYY is the designation of an increasingly violent behavior towards criminals.
